VALVE.

Application led October 15, 1913.

T all whom t may concern:

i- Be it known that I, PETER G. MACGREGOR,

a citizen of the United States, and resident .of the city, county, and State of New York,

by have invented certain new and useful Imtinguisher of the type in which air is introduced under pressure to operate the fire extinguisher. The air exerts a pressure upon the fire extinguishing liquid and forces the same out through a peculiar system of valves, all of which will be described more fully hereinafter in connection with -the description of the invention as illustrated in the accompanying drawings.

Figure l is a sectional side elevation of a fire extinguisher embodying the invention. Fig. 2 is an enlarged sectional view of the lower portion of Fig. 1. Fig. 3 is a sectional view on the line 3 3 of Fig. 2,"showing the 'valve in another position. p q

A container or receptacle 1, preferably cylaindrical in form, contains the fire extinguishing fluid. A centrally mounted shaft 2 positioned in the receptacle 1, the same being hollow for a portion of its length, coni- Vmunicates withl an opening 3, extending through the lower end of the receptacle 1, and a valve 1. This valve isl of peculiar' construction and not only controls the open ing from the receptacle l but is also arranged so that compressed air may be admit ted therethrough or air pumped into the receptacle for producing the air pressure for forcing the fire extinguishing liquid `out when the device 'is inl use. y

The valve body 4 is provided with a lon- Specication of Letters Patent.

gitudinal opening 5 forming a continuation of the opening in the tubular shaft 2 and the opening 3 when the valve plug 6 stands in the position shown in Figs. 1 and 2, in which position the liquid passes out through the transverse opening in the plug 6. A second opening 7 in the plug 6 eXtends from this last named opening at right angles and forms a communication with the passage 5 when the valve plug 6 stands in the position shown in Fig. 3. An air valve of any suitable construction is positioned in the longitudinal opening 8 in the plug 6, at the outer end of which connection may be made with a pump or compressed air supply when the cap is removed. It will thus be seen that when the valve plug 6 is turned to the position shown in Fig. 3 air may be pumped to the interior of the receptacle 1 which will produce a pressure on the liquid therein and force the same out when the valve plug 6 is turned to theyposition shown in Figs. l and 2.

lVhat I claim is In a valve for fire extinguishers a body provided with a longitudinal opening forming an outlet for the fluid and a plug provided with two transverse openings and a longitudinal opening, andan air inlet valve.

positioned in said longitudinal opening in said plug.
